The man who wrote Brave New World also wrote a children's book? Yes! I had no idea. Maria Popova provides a synopsis:

The Crows of Pearblossom tells the story of Mr. and Mrs. Crow, whose eggs never hatch because the Rattlesnake living at the base of their tree keeps eating them. After the 297th eaten egg, the hopeful parents set out to kill the snake and enlist the help of their friend, Mr. Owl, who bakes mud into two stone eggs and paints them to resemble the Crows’ eggs. Upon eating them, the Rattlesnake is in so much pain that he beings to thrash about, tying himself in knots around the branches. Mrs. Crow goes merrily on to hatch “four families of 17 children each,” using the snake “as a clothesline on which to hang the little crows’ diapers.”

Gertrude Stein, Salman Rushdie and other surprising people also wrote children's books. Read about them at the link.
